Definitions

  • This invention relates generally to structures supporting optically correct prescription lenses for those who must wear protective masks, and more particularly to a support structure designed to be used with foldable protective masks and to accurately locate and facilitate replacement of prescription or otherwise specialized lenses.
  • This invention may be used by those requiring vision correction and also having to wear protective masks, such as gas masks, full face respirators or welding helmets, scuba goggles, ski goggles, luge helmets and surgical masks, where ordinary spectacles with temples are impractical.
  • a loop of wire or metal is attached to each frame at the location where normally a temple hinge would be found. These loops extend forward of the lenses and toward the center.
  • the protective mask has a bracket near the center of the top of the face plate designed to receive the ends of the loops.
  • the spectacles are suspended from the inside surface of the mask, by the metal loops.
  • the loops are approximately one and one half times the diameter of each lens.
  • This metal retaining ring method has several disadvantages. Prescription lenses must be located properly to insure that the lenses will provide the optimum corrective benefit. Several terms must be defined to describe proper fitting of prescription lenses.
  • the "eye-wire” is that part of the frame that encircles and retains an individual lens.
  • the "vertex position” is the vertical position of the lens centers with respect to the pupils.
  • the "pantoscopic angle” is the angle by which the vertical axis of the lens is inclined to a nominal vertical reference with respect to the wearer's face.
  • the "face-form” angle is an angle between two planes. The two planes that defined the face-form angle are the respective planes in which the perimeters of the eyewires lie.
  • the lenses cannot be located accurately in front of the eye to afford optimum visual correction. It is also difficult to maintain the proper pantoscopic angle because of the inherent flexibility of the structure. Thus optimum visual correction is not provided. Similarly, proper face-form angle cannot be maintained due to the spring nose-piece. Vertical adjustment of the lenses is difficult. If the retaining rings are removed from the mask, it is difficult to reposition the lens carrier in the proper vertical position. Finally, lenses cannot be removed from the frame without using special tools, and without removing the lens carrier from the protective mask.
  • a lens carrier support anchor is cemented to the inside surface of the face plate, or to the structure which supports the face plate.
  • the anchor piece is designed to receive a semi-flexible tab-like member which is integral with the nose bridge of a spectacle frame.
  • the frame has no temples.
  • Disadvantages of this system are that the relatively flexible tab does not secure the spectacle frames in a secure position, so that the pantoscopic angle can not be fixed. Further, the face-form angle is not easily customizable. Further, it is not possible to fix the vertical adjustment, or the horizontal distance from the pupils to the lenses. Finally, a face mask that may be folded flat when not in use, may not be folded flat when this type of a lens carrier is used.
  • the support anchor attaches to the face plate with a suction cup.
  • this device may be used only for brief periods of time, and is not recommended for dangerous situations because the suction cup may disengage at any time.
  • the several objects of our invention include providing a support structure for protective face mask optcial inserts by which: accurate, stable positioning of the optical insert may be obtained; the optical insert may be removed from one mask and easily positioned and attached to another mask; proper pantoscopic and face-form angles may be achieved; proper vertical placement and pupil to lens distances may be achieved; the lenses may be easily removed and replaced without removing the support structure from the mask; the mask and lens support structure may be folded flat while not in use and safe, reliable positioning of the optical inserts may be accomplished.
  • This invention comprises a lens support that attaches to the inside of the face plate of a protective mask. It may be used with either single plate face masks, or face masks that may be folded flat, having two face plates.
  • the invention comprises a pair of lens frames joined by a hinge that makes up the nose bridge. Each individual lens frame is made up of an eyewire integrally formed with an element that makes up part of the hinged nose bridge.
  • the hinge permits folding the pair of lens frames together so that the portions of the lense frames furthest away from the nose bridge almost touch.
  • the hinged pair of lens frames attaches to a hinge block having a dove-tail type projection on the side facing away from the lens frames.
  • the projection engages a back block provided with a suitably sized dove-tail groove.
  • the back block attaches to an anchor that attaches to the face plate or to the mask adjacent the face plate.
  • the presciption lenses are rigidly secured to the face mask through the dove-tails of the front hinge block and the back block
  • the face of the back block that attaches to the anchor, and the opposite face of the back block, that engages the dove tail hinge block, are angularly disposed with respect to each other to provide the pantoscopic angle required by the particular wearer and mask.
  • the cooperation of the front hinge block and the front surface of the hinge element of each lens frame may be customized to limit the hinged travel of the pair of lens frames, thereby adapting properly to the wearer's required face-form angle.
  • the lens support may be folded flat when used with a protective mask which may be folded flat during non-use. Further, the lens supporting frames may be folded inward, and the lenses may be removed by popping them out from the rear.
  • a lens and lens frame system which permits snapping a lens into the lens frame from the front with only finger pressure, and also removing the lens by simply snaping the lens out, is described in the Assignee's co-pending co-assigned U.S. application Ser. No. 742,884, filed on June 10, 1985, in the name of Clark Grendol.
  • FIG. 1 shows schematically prescription or specialized lenses used in conjunction with a protective face mask.
  • FIG. 2 shows an exploded isometric view of the components of our invention.
  • FIG. 3 shows an isometric view of the components illustrated in FIG. 2, assembled.
  • FIG. 4 shows an elevation side view of the back block, shown in FIG. 2.
  • FIG. 5 shows a plan view of our invention, with both lens frames folded back and one lens removed, in partial cross-section.
  • FIG. 6 is a plan view of two different left lens frames, each adapted to assemble into frame providing a different face-form angle.
  • FIG. 1 shows schematically a person wearing a protective face mask, and also using prescription or special lenses carried by a lens support. It can be seen, that once the mask is in place, adjustment of the lens support is impossible. Therefore the lens support must be secured so that the position relative to the user's eyes is reproduceable. Further, it can be seen that standard eye glasses with temples are impractical and uncomfortable, due to the wrap-around features of the protective mask.
  • FIG. 2 shows an exploded view of the elements of a preferred embodiment of our invention.
  • Elements 1 are a pair of lens carrying frames, each frame made up of an eyewire 2 and a hinge portion 4.
  • the eyewires are of a type designed to releasably engage lenses merely by snapping the lenses into place from the front.
  • the eyewires are provided with a series of tabs (not shown) around the forward aperture of the eyewire, which engage the lens when the lens is snapped into place.
  • This type of eyewire and lens system is described more fully in co-pending, commonly assigned application Ser. No. 742,884, filed on June 10, 1985, in the name of Clark Grendol.
  • the frame portions 1 are provided with mating hinge lobes 3 and 5.
  • each lens frame is provided with a hole 7 designed to receive the arms 9 of a pair of torsion springs 11.
  • the two lens frames are fit together with hinge lobe 5 sliding between hinge lobes 3.
  • the torsion springs 11 are fitted into holes 7 on the top and bottom of the frames. When so joined, the spaces 17 formed by the looped torsion springs align with holes 13 and 15 in the hinge lobes 3 and 5 respectively.
  • Front hinge block 19 secures the torsion springs and the lens frames between upper and lower hinge block lobes 21 like a sandwich.
  • Hinge pin 23 passes through holes 25 in hinge block lobes 21 and through spaces 17 in torsion springs 11 and holes 13 and 15 in hinge lobes 3 and 5.
  • the hinge pin 23 may be secured by threading into the lower hinge block lobe 21, by plastic heat fusion methods, by a threaded nut (not shown) or by any well known means.
  • the vertex position of the lens frames is established by placing the front hinge block 27 in the proper vertical position with respect to the backblock 25. As described below, the back block is rigidly fixed with respect to the mask.
  • the front hinge block is provided with a dove-tail projection 27, which slideably engages the dove-tail recess 29 in back block 25.
  • Set screw 31 secures the hinge block in the proper vertical location.
  • the back block and anchor piece 33 are attached to the protective mask. This may be accomplished by several means.
  • the anchor 33 may be permanently attached to the structural element by any suitable means, including adhesives, heat sealing, or mechanical means.
  • the back block 25 is permanently attached to the anchor piece 33.
  • the back block is made up of a solid having a trapezoidal cross-sectional, with a dove-tail groove along one of the longer faces. As can be seen in FIG.
  • the forward face 35 (facing the anchor) is inclined with respect to the rearward face 37 (facing the hinge block).
  • Changing this angle A permits customizing the pantoscopic angle.
  • the pantoscopic angle must be customized for each particular user, and further, if the user uses different protective masks having different structures, it may be necessry to realign the placement of the lens carrying support structure with respect to the mask and the portions of the support structure that anchor the lens carrier to the mask. Therefore, several different back blocks may be used by each user.
  • each lens frame is made up of a hinge portion 4 adjacent the hinge lobes, and an eyewire 1 which generally surrounds the lens.
  • the hinge portion 4 contacts the face plane 43 of the front hinge block.
  • An eyewire angle f is defined by the intersection of the front surface of the hinge portion 4 and the forward plane of the eyewire 1.
  • the eyewire is inclined at eyewire angle f with respect to the face plane 43.
  • This eyewire angle f defines the face-form angle.
  • the proper face-form angle may be obtained by properly preparing the eyewire angle f.
  • This angle is either molded into the frames during fabrication, or, alternatively, it may be applied by heating and bending the frame during initial fitting of the frames.
  • a user desiring to exchange lenses either to obtain a different prescription, or to obtain different lens characteristics, such as color, polarization, or composition simply folds the lens frame away from the face plate of the mask, and snaps the lens out from the lens frame pushing from the rear to the front (in the direction of the arrow X).
  • the user inserts a replacement lens from the front of the rear and unfolds the lens frames back to the original position.
  • This feature is also advantageous if the protective face mask becomes damaged, and the user needs to remove the lenses to another face mask and lens carrier combination. Again, the lenses may be removed, and snapped into place in another mask. This feature reduces the cost of outfitting a user with a wide variety of masks, as the cost of manufacturing the prescription lenses must only be borne once.
  • each mask may be outfitted with the lens carrier support structure, but without any lenses. In that case, the user supplies the lenses, and exchanges them from mask to mask. This assumes that the lens carrier structure has been installed in such a way that when the lenses are inserted, the pantoscopic, face-form and other measurements will be proper.
  • each mask need only be outfitted with the anchor 33 and a back block 25, with an appropriately designed angle. Then, the lens carrying frame structure, including the frames 1 and the hinge block 21, may be removed from a particular mask, and placed into another type of mask by engaging the dove-tail projection. In this case, a minor adjustment must be made to insure proper vertical placement.
  • the pantoscopic angle may be precisely adapted for the individual wearer and mask combination. Once installed in the face mask, this angle will not be altered by the user.
  • the face-form angle is also precisely adaptable for the particular wearer.
  • the vertical adjustability feature allows for the vertex dimension to be set and maintained.
  • FIG. 5 contemplates a permanent fixture of anchor 33 to the structural area between the left and right face plates of the face mask.
  • the invention may also be practiced with a single face plate type mask.
  • the anchor 33 would either be attached to the face plate with adhesive, or attached to a structural portion of the mask immediately adjacent the central upper edge of the face plate.
